Specification of Letters Patent.

Patented Nov. 18, 1913.

Application filed October 25, 1913. Serial No. 727,671.

To all whom it may concern:

Be it known that I, CHARLES E. Reno, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Pattern-Gradin Machines, of

which the following is a specification.

My invention relates more especially to the type of pattern-gradingmachines employing an adjustable pantographic frame and model-tracingand pattern-producing elements carried thereby.

My primary objects, generally stated, are to provide, in a machine ofthe pantographic type and employing a traveling cutter-head, for thechanging of the position of said head, as desired, relative to the1nodel-tracer to permit additions forming laps, folds, or cloth-seams,to be produced, from a net model, on the patterns made therefrom, orproduce from a model having an addition or additions patterns having noadditions, and to produce patterns of the characters above statedwherein the additions or subtractions on the patterns relative to themodels will be of uniform width regardless of the number of difierentsizes of patterns made from the model and whether the patterns to bemade are lar er or smaller than the model, all without cisturbing thecenters or sizesettings of the pantographic mechanism 111 making theadjustments for such additions or subtractions; to provide improvedmeans for use in any type of pantographie patternproducing machine, forproducing additions and subtractions relative to the models, on patternswithout disturbing the pantographic centers and size-settings; toprovide, generally, in pattern-producing machines of the pantographictype, for the production from one model of patterns for different widthsof shoes, with the correct graduations for length and width necessary toproduce the correct grade for either width, regardless of the patternsbeing larger or smaller than the model; and furthermore, if desired,permit shoe-patterns of all sizes and widths to be produced from asingle model.

leferring to the accompanying drawings- Figure 1 is a plan View of amachine of the pantographic type and employing a traveling cutter-head,equipped with my improvements, a part of the machine being broken away.Fig. 2 is a section taken at the line 2 on Fig. 1 and viewed in thedirection of the arrow. Fig. 3 is a plan view of a portion of thestructure illustrated in Fig. 1. Fig. 4 IS a plan view of the movablepantographic frame and parts carried thereby, certain of which areillustrated in section and others thereof broken away, the section beingtaken at the line 4. on Fig. 2 and viewed in the direction of the arrow.Figs. 5 and 6 are enlarged sections taken at the lines 5 and 6,respectively, on Fig. 1 and viewed in the directions of the arrows.Figs. 7 and 8 are enlarged sections taken at the lines 7 and 8,respectively, on Fig. 1 and viewed in the directions of the arrows.

Fig. 12 'is a plan view of aplurality of patterns produced from a machine embodying my improvementsand from which the quarters for Blucher shoes of graduated widths may bemade, the patterns being superposed to illustrate the variations in thepatterns for the different widths, the graded additions on the rearedges thereof being slightly exaggerated. Fig. 13 is a broken view invertical sectional elevation through the static-nary and one of themovable frames of the machine showing the pattern cutting mechanism inelevation; and Fig. 1-1, a View in front elevation of the ilnachineshown at the right-hand side of As the machine in connection with whichI have chosen to illustrate my invention is as to its general featuresof construction, 0 a type commonly used in the manufacture of shoepatterns, it is unnecessary that I describe all the details of themachine, a general description only as follows being neces* sary.

The stationary frame of the machine is represented at 9 and is equippedwith rollerengaging guide-surfaces 10 for the rollers 11 of the frame 12freely movable on the rollers back and forth on the frame 9. The frame12 is provided with roller-engaging guidemembers 13 for rollers 14 and15 on a pair of frames 16 and 17, which are freely movable on the frame12 at right angles to the movement of the latter, the frame 16 beingprovided with roller-engaging guide-surfaces 18 for rollers 19 on aframe 20, forming the cutter-head, and surmounting the frame 16 andmovable back and forth on the latter. The frame 17, as is usual inpractice, carries the model-tracing element represented at 100 which inthe operation of the machine is manually moved by the operator againstthe peri ahery of a pattern-model, as for examp e, the model shown'at101 and which is cated at 21 and 22, are grading levers 23 and 24,respectively, in the form of quadrants, the lever 23 at its right-handend (Fig. 2) being pivoted, as indicated at 25, to a coupling-member 26pivoted, as indicated at 27, to a carriage 28 guidedly carried byrollers 29 on a cross-bar 30 supported on the stationary frame 9, andthe rear end of the lever 24 being pivotally connected at 31 with theforward end of a connecting link 32 pivoted at its rear-end, asindicated at 33, to a block 34 slidably confined to move back and forthon a guide'35 on the frame 12.

Mounted on the levers 23 and 24 are clamping-heads 36 and 37,respectively, these heads being adapted to be adjusted to any desiredposition along the levers and clamped in adjusted positions thereon, asby clamping'means 38, in accordance with common practice. The frame 16is connected with the clamping-head 37 through the medium of a radiusbar 39 pivotally connected at one end, as indicated at 40, to the frame16 and at its opposite end, as indicated at 41, to the head 37, thisbar, in accordance with my invention, being formed of sections 42 and 43adjustably connected together, as hereinafter described. The frame 20 isconnected with the clampinghead 36 through the medium of a radius bar 44which is pivotally connected with the frame 20, as indicated at 45, andwith the head 36, as indicated at 46, this bar, in accordance with myinvention, being formed of relatively-adjustable sections 47 and 48adapted to be held in adjusted position by the means hereinafterdescribed.

As is well understood in the art, the adjustment of the various movableframes referred to and their connecting parts for cutting patterns ofdifferent sizes from a single model, is effected by adjusting theclampingheads 36 and 37 on the respective levers 23 and 24, andadjustments for producing irregular grades are produced by adjusting thelevers 23 and 24 relative to the connectors 26 and 32, respectively, tovary the angular relations at which these parts extend relative to eachother, clamping means, as for example, those illustrated at 49 beingemployed for rigidly holding the said levers and connectors in adjustedposition.

In the construction illustrated, the bars 39 and 44 are adapted to belengthened and shortened, as desired, and held in such adjusted positionfor the purpose of adjusting the frames 16 and 17, and 16 and 20,relative to each other, for the purpose hereinafter explained, and tothis end, I prefer to construct these bars, and provide clampingmechanism therefor, as illustrated in the drawings and of which thefollowing is a description: The section 42 of the bar 39 terminates in adovetail tongue 50 whichbar-section 43. The upper threaded end of thebolt 53 carries a nut 60 which operates, when screwed down, upon thebolt 53, to

draw the tongue 50 into tight frictional engagement with the undercutwalls 51 of the groove 52 and thus frictionally clamp t0- gether thesections 42 and 43 of the bar 39, it being understood that thesebar-sections may be adjusted lengthwise of each other by swinging thelever 56 onits pivot 57, and, if desired, a scale 61 may be provided onthe bar-section 42 for coiiperation with a pointer 62 on the bar-section43, or, if desired, the positions of the scale 61 and pointer 62 may bereversed, or a scale (not shown) may be provided on an arc-shaped bar 63for cotiperation with the swinging end of the lever 56. The sections 47and 48 of the bar 44 are connected together, as follows: The bar-section47 is-formed (at its forward end) with a dove-tail tongue 64,interfitting with a. dove-tail groove 65 in the bar-section 48. A bolt66 has screw engagement at its lower end, as indicated at 67, with thetongue-end of the bar-section 47 and passes up through a lever 68,wherein it has journal, fit, pivoted, as indicated at 69, to a link 70,pivoted to the bar-section 47, as indicated at-7l, the upper end of thebolt 66 being headed, as indicated at 72, and provided with a fingergrip 73, whereby the bolt 66 may be screwed up or down in the section47. The underside of the tongue 64 is counter-bored, as indicated at 74,and contains therein a block 75 resting on the bottom of the groove 65,the bolt 66 c6oper ating with said blockand-serving, when said bolt isscrewed down, to cause the tongue 64 to be forced upwardly into clampingenagement with the walls of the groove orreleasably clamping thesections 47 and 48 together in adjusted positions. It will thus beunderstood that the bars 39 and 44 are' thus rendered in effectexpansible and contractible for adjusting the frames 16 and 17 and-theframes 20 and 16, respectively, relative to each other.

It will furtherbe understood that by adjusting. the sections 42 and 43,of the'bar 39, the frame 16, with all the operative parts carriedthereby,-may be shifted to the right or to the left-in Fig* 9, relativeto the frame 17, asdesired, for producing on the pattern,

at either or both opposite .sides thereof, a lap or laps, as the casemay be, of the desired width, it being understood that to produce lapson both of opposed sides of the pattern, the bar 39 must be adjusted to.throw the frame 16 to one side of its normal position for producing alap on one side of the pattern, and when said lap has been produced,must throw the frame 16 in the opposite direction beyond its normalposition to produce a lap on the opposite edge, Figl1 of the drawingsshowing two superposed patterns for the quarter of a Blucher shoe, theuppermost pattern represented at 76 beinghunprovided with such anaddition, and used where the pattern is to be used: in cutting thequarter from lea:t l 1er, whereas the lowermost pattern 77, whichls-usedin cutting the quarter from fabric wherein provision for a greaterseammust lee-made, is provided with such an addition represented at 78,produced by shifting. the frame 16 and consequently the pattern-cutterto the left in Fig. 4 and as represented by dotted lines of thebar-section 42 at the left in Fig 9, before cutting the left-hand edgeof the pattern. By adjustingv the bar-sections 47 and 48 relative toeach other, as hereinbefore stated, the frame 20 maybe adjusted back andforth relative to the frame 16 and thus a lap or laps may be produced onthe'patt'erns at the opposed sides thereof other than those the forma-.ti-on of the laps on whichare controlled by adjusting. the: sections ofthe bar 39, and where the production of a lap of such shape is requiredas to involve both len th and width adjustments of the frames, t is mayeabe' effected by a combination of adjustments offthebars 39 and-44. g h

In Fig. 12:1 have illustratedfivesuperposed patterns made from themachine for the quarters of 65 One of which, for example, is of modelsize,

Blueher shoes the middle graduated successively to different widths butall for the same length of shoe. For each width the pattern must bemade. slightly larger or smaller throughout certain of its portionswhere it is to be respectively larger or smaller than the model size,and not only must the edges of the patterns at which the additions orsubtractions, as the. case may be, occur at certain portions thereof,taper and merge into the edges of the patterns, as represented, inexaggerated condition, at 79, but certain of the additions orsubtractions, as the case may he, required to be made, occur alongcurved surfaces of the patterns, as represented at 80, and are ofdifierent widths at their opposite ends as indicated at 81 and 82. Itwill be understood that the additions or subtractions, relative to themodel, and represented at 83 and 84-, alon the straight or comparativelystraight sides of the patterns are made by shifting the cutter-headframe relative to the model-tracer by shifting the frame 20 relative tothe frame 16 in the appropriate directions, as hcrcinbefore set forth,but in a single direction for cutting each side, Whereas the productionof additions or subtractions relative to the model along the curvedlines, as for example, the additions and subtractions 80 require acombination of adjustments of the cutter equipped frame relative to thetracer elements as by adjusting the sections of both bars 30 and 44, toshift the cutter-head into the proper position relative to the tracer,thus adjusting the cutter-head causing the edges of the portions 81 and82 to merge into each other, as distinguished from forming ana'bruptoffset where the portions 81 stop and the portions 82 begin.

By the use of the adjustments between the sections of the bars 39 and 44not only may additions and subtractio-ns, relative to the model, be madeon any portion of a pat tern reduced otherwise the same as said mode,but by the same ad'justmcntsthe same additions or subtractions,non-graded in width, may be made on all sizes of patterns made from saidmodel, without disturbing the centers or size-settings of the machine:Furthermore, it will be readily understood that by reason of the dualadjustments of the sections of the bars 39 and 44, which permit ofadditions or subtractions being made at all sides of the pattern,patterns of'diiferent widths, with all of the re uired dimensions,includingthose of the an (1e and instep and whether larger or smallerthan the model may be made from the same net model, and, ifdesired, allsizes and widths of patterns may.- be made from the same net model.

While I have showna machine 1n which the connecting means between thegrading levers23and 24 and the frames 20 and 16,

respectively, are rendered expansible and contractible, and securable inadjusted position by certain specific mechanism, I do not wish to beunderstood as intending to limit my invention to the employment of suchspecific mechanism, as any other mechanism suitable for this purpose maybe em-- ployed; and furthermore, I do not wish to be understood asintending to limit my invention tothe use of the specific clamp-in meansemployed for both the bars 39 and 44, as such mechanism may be used in amachine in'which adjustment of abut one connecting member is providedfor. Furthermore it will be readily understood by those skilled in theart that certain features of my inventionare useful in machinesemploying a vpattern-marking element wherein the pattern is merelymarked on the blank to material, as well as in machines employing meansfor cutting out the patterns from the blanks. Accordingly certain of thefollowing claims refer to a pattern-forming element and by suchdesignation I wish to be 5 understood as intending to claim either H apattern-marking or pattern-cutting element.
